The constructor.

Method Detail

getNext

public NODE getNext()

This method gets the next node of the linked list.

Specified by:

getNext in interface LinkedNode<V,NODE extends AbstractLinkedNode<V,NODE>>

Returns:

the next node or null if this is the last node (tail).

setNext

public void setNext(NODE next)

This method sets the next node.

Parameters:

next - is the next to set. May be null to indicate that this is the last node of the list.

getValue

public V getValue()

This method gets the actual value of this node.

Specified by:

getValue in interface LinkedNode<V,NODE extends AbstractLinkedNode<V,NODE>>

Returns:

the value, may be null.

setValue

public void setValue(V value)

This method sets the value.

Parameters:

value - is the value to set. May be null.

isLinked

public boolean isLinked()

This method determines if this node is linked. A node is linked if it has a next node.

Specified by:

isLinked in interface LinkedNode<V,NODE extends AbstractLinkedNode<V,NODE>>

Returns:

true if linked, false otherwise.

addToList

public void addToList(List<V> list)

This method appends the values of the list represented by this node to the given list.
Call this method on the head-node with an empty List to convert a LinkedNode-list to a regular List.

Specified by:

addToList in interface LinkedNode<V,NODE extends AbstractLinkedNode<V,NODE>>

Parameters:

list - is where to append the values.

toList

public List<V> toList()

This method converts the list represented by this node to a regular List.

Specified by:

toList in interface LinkedNode<V,NODE extends AbstractLinkedNode<V,NODE>>

Returns:

the List of all values of the list represented by this node.

toString

public String toString()

Overrides:

toString in class Object
